US2066 Driver.

Anyone know of a US2066 Driver ? I'm messing around with a 4x20 NHD oled with no luck.

This one can be easily translated to CCS:
https://github.com/NewhavenDisplay/NHD_US2066

DigitalWrite() in Arduino translates to output_bit() in CCS.
Delay() in Arduino translates to delay_ms() in CCS.

Example:

Arduino code:
Code:

void command(unsigned char c)
{
  unsigned char i, temp;
  switch(mode)
  {
    case 0:   digitalWrite(CS, LOW);
              PORTA = c;
              digitalWrite(RS, LOW);
              digitalWrite(E, HIGH);
              delay(1);
              digitalWrite(E, LOW);
              digitalWrite(CS, HIGH);
    break;

Translated to CCS:
Code:

#define LOW 0
#define HIGH 1

#define CS  PIN_B0   // Or whatever pins you are using for it
#define RS  PIN_B1
#define E   PIN_B2

#byte PORTA = getenv("SFR:PORTA")  // Use LATA if using PIC18F
unsigned char mode = 0; // 0 = 8-bit parallel 6800 mode; 1 = i2c mode; 2 = SPI mode;
const char slave2w = 0x78;  // CCS uses 8-bit slave address


void command(unsigned char c)
{
unsigned char i, temp;

switch(mode)
  {
    case 0:  output_bit(CS, LOW);
             PORTA = c;
             output_bit(RS, LOW);
             output_bit(E, HIGH);
             delay_ms(1);
             output_bit(E, LOW);
             output_bit (CS, HIGH);
    break;

  }
}
